BLEACHING COTTON IN THE FORM OF COPS.

' SPECIFICATION forming part of Letters Patent No. 254,386, dated February 28, 1882,

Application filedSeptember 27, 1881. (No model.)

To all whom it may concern Be it known that I, EMANUEL RUscH, of Pottendorf, near Vienna, in the Empire of Austria, have invented certain new and useful Improvements in Bleaching or Dyeing Yarn in Oops, of which the following is a specification.

Heretoforeit has not, so far as known to me,

been practicable to produce bleached or dyed dle, andthereby compact the yarn and prevent the bleaching or other liquid from reaching the interior of the cop, and even if the cop be wound on a fluted or grooved spindle, or transferred after winding to a fluted or grooved spindle of the same diameter as that on which it was wound,the shrinking of the yarn will cause it to hug the ridges between the flutes or grooves, and thereby not onlycompact the yarn on the ridges themselves, but also produce a tension on the yarn across the flutes, and so prevent the bleaching or 0th erliquid from thoroughly and evenly penetrating the cop from the inside.

According to my invention I place the cop, after winding, upon ableachingspindle or spool the external diameter of which is smaller than that of the hole in the cop, providing for a clear annular space all around between the cop and the spindle or spool, and I then place the spindles or spools, with the cops upon them, in a vessel or vat, wherein they are acted upon by the bleaching or other liquid,'and thus provide for the ready and simultaneous access of liquid to the interior and exterior of the cops, and allow the cops to be freely penetrated by the liquid.

The invention further consists in the combination, with a cop and its winding-bobbin, of a bleaching-spindle having a smaller external diameter than said bobbin.

The invention also consists in novel devices for transferring the cops from the bobbins on highly polished externally. tubular bobbins A should be so shaped-as to which they are wound to the-smaller spindles or spools. 1

In the accompanyingdrawings, Figure 1 represents a longitudinal section of abobbin upon which the cop is wound, and Fig. 2 is an end view thereof. Fig. 3 is a longitudinal section of a tubular device which I employ in transferring the cops from the windingbobbins to thebleaching-spindles, and Fig. 4 is an end view thereof. Fig.5 is a side view of a beaching-spindle, and Fig. 6 is an end view thereof. Fig. 7 is a longitudinal section of a cop, the bobbin on which it is wound, the tubular device for transferring it, and a side view of the bleaching-spindle,showingthemanneroftransferring the cop. Fig. 8 is a longitudinal section of a cop and a side view of a bleachingspindle on which the cop is placed, and Fig. 9 is a plan of the cop and bleaching-spindle.

Similar letters of reference designa-e corresponding parts in all the figures.

In bleaching oops I take the fiber after it has been carded, drawn, and somewhat twisted, and 1 wind the roving or yarn upon a tubular bobbin, A, which may be made of wood, earthenware, glass, ebonite, or othermaterial, and The ends of the readily engage with the winding f1 ame or machine, and in the present example of my invention are notched at a.

B designates the bleachirig-spindle, which may be made of wood or other material calculated to resist more or less thecorrosive action of the bleaching or other liquid. 'lliisspindle has at the lower end a base or foot, B, and it is considerably smaller in diameter than the exterior of the bobbin A, so that it can be readily inserted into the hole in the c p after the latter is slipped ofl' the bobbin A. The bleachingspindle B may have longitudinal external flutes, corrugations, or grooves, 12; but I do uotconsider these necessary; and it may also have a hole or bore at the center to enable it to fit the spindle or skewer ot' a spinning-frame,'in which the cops, with the spindles B in them, may be placed after bleaching and drying.

In transferring the cop from the tubular bobbin A, on which it is wound, to the bleachingspindle B, I may employ the device shown in Figs. 3 and 4,which consists of a tube,0,having at one end an extension, G, of smaller diameter.

The tube 0 should be externally somewhat less in diameter than the external diameter of the bobbin A, and of a size to freely receive the. spindle B within it, and the tubular extension U should be externally of a size to fit easily in the tubular bobbin A. The tube 0 C may be made of metal or other material.

In transferring the cop D from the windingbobbin A and onto the bleaching-spindle B, I place the bleaching-spindle inside the tube 0, and insert the tubular extension 0 into the bobbin A, all as shown clearly in Fig. 7. By a downward pressure or pull the cop D is then drawn off from the bobbin A and onto the tube (J, as shown in dotted outline in Fig. 7, on which it fits loosely because of the tube being externally smaller in diameter than the bobbin A. lhe tube (3 is now lifted off, leaving the cop D on the spindle B, whereon it fits very loo.-ely, as shown in Figs. 8 and 9, a clear annular space, 0, being left all around between the cop and the spindle throughout the entire length of the cop.

Although the cop may be very readily transferred from the winding-bobbin to the bleaching-spindle by the aid of the tube 0, it may be i done in various other ways, The cops are now ready to be bleached by any one of the simple methods practiced in bleaching yarn in hanks. The bottom of the vessel or keir may be first completely covered with spindles having cops upon them, and which may stand upright, side by side, a free space being left below them by means of a perforated false bottom, as usual. Then,ifhanks are to be bleached at the same time, the spindles may be covered with alayer of banks. Then Iarrangeasecond layer of spindles, and so on alternately until the vessel or keir is filled.

In case cops alone are to be bleached, the several layers ofspindles may be separated by perforated trays, and the last layerof spindles is covered with a weighted perforated tray or with ordinarypacking-cloth or other substance. The washing, bleaching, and drying now goes on in the usual well-known way as in bleaching banks. In case keirs are used, which can be hermetically closedas, for instance,in the case of a vacuum apparatusthe Whole process may be considerably shortened, produc ing a great improvement in the bleachingof the fiber by enforcing the discharge of the bleaching or washing liquid by means of airpressure produced either by an air pump or injector. In such case the presence of air resists greatly the development of gaseous chlorlne.

When a bluish or other tinge of the yarn is desired the cops, instead of going after the bleaching to the drying-room, are once more put into the bleaching vessel or keir, arranged as before described, and are soaked with a solution of indigotine or other desired coloringmatter. They may be then removed and freed from water by the action of a centrifugal machine or otherwise, and taken to the dryingroom. Any irregularities in the bluing disappear entirely in the finished cops by reason of the many doublings that take place in the further spinning of the sliver.

I am aware that it is old to bleach and dye 'cops by placing them upon hollow perforated skewers or spindles which communicate at their ends with a pipe through which the bleaching or dyeing liquid is injected or forced into the hollow skewers or spindles, and thence into the cops; and I am also aware that such skewers or spindles have been fluted or grooved in order to better expose the interior of the cops to the action of the liquid; and I do not therefore claim broadly the placing of the cops on separate spindles for bleaching or dyeing. In this oldmethod, however, the cops fit snugly on the skewers or-spindles, and even though the latter be fluted or grooved the swelling of the yarn when wet will cause it to be drawn tightly upon the ridges between the duties or grooves and kept at a tension across the flutes, and thereby the cop will be compacted internally to such an extent as to prevent the liquid from rapidly, thoroughly, and uniformly penetrating all parts of the cop, as it can both from the interior and exterior simultaneously when a clear annular space is left all around between the cop and spindle, and the cop fits very loosely on the spindle even when wet, as in my case.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The method of bleaching or dyeing cops, consisting in placing the cop, after winding, upon a bleaching spindle or spool which has an external diameter less than that of the hole in the cop, providing for a clear annular space all round between the cop and spindle or spool, and then placing the spindle or spool, with the cop upon it, in a vessel, wherein it'is subjected both internally and externally at the same time to theaction of bleaching or other liquid, substantially as herein described.

2. The combination, with a cop and its winding-bobbin A, of a bleaching-spindle, B, having a smaller external diameter than said bobbin, substantially as herein described.

3. The combination, with the winding-bobbin A aud spindle B, of the tube (3, with the extension 0, substantially as herein described.
